Terconazole is an antifungal drug used to treat vaginal yeast infection. Terconazole may exert its antifungal activity by disrupting normal fungal cell membrane permeability. Terconazole and other triazole antifungal agents inhibit cytochrome P450 "14-alpha-demethylase" in susceptible fungi, which leads to the accumulation of lanosterol and other methylated sterols and a decrease in ergosterol concentration. Depletion of ergosterol in the membrane disrupts the structure and function of the fungal cell leading to a decrease or inhibition of fungal growth. During controlled clinical studies conducted in the United States, 521 patients with vulvovaginal candidiasis were treated with terconazole 0.4% vaginal cream. Based on comparative analyses with placebo, the adverse experiences considered most likely related to terconazole 0.4% vaginal cream were a headache and body pain. Fever and chills, vulvovaginal burning, itching, and irritation have also been reported. The adverse drug experience on terconazole most frequently causing discontinuation was vulvovaginal itching.

In Vitro Use Guide

Terconazole was dissolved in methyl alcohol to a final concentration of 250 mkg/ml. 20 mkl of these solutions were added to 6 mm blank antibiotic discs (BBL) and dried at room temperature to yield 5 mkg/disk. The disks were applied to the inoculated surface of a two-layer agar assay plate (150 mm dia.). The base uninoculated layer contained 42 ml of the supplemented agar selected for the study. The agar selected was TSA containing 16 mkg/ml biotin, sodium chloride. 1.5% (w/v), pH 7.4. The inoculated top layer consisted of 8 ml of the same agar. The final cell count was 6.4 X 10^4 colony-forming units (CFU)/ml of agar. Within 30 min of preparation of the agar plate, disks of each of the test compounds were placed on the agar surface and the plates incubated 48 h at 37.5 °C. The zones of inhibition were measured to the nearest 0.5 mm
